Using Capacitor, how can I prevent quasar forcing the dev server to an external IP?

[inkysquid]

For Android development, I'd prefer to use the adb reverse proxy so that the dev server is accessed via localhost on the device. This gives me the following benefits:

• Can develop when not connected to a network.
• Avoids capacitor.config.json changes cluttering commits and causing merge conflicts.
• Gives me a single host to whitelist (localhost)

I'm currently achieving this by running the following:

node patch-quasar.js
adb reverse tcp:9500 tcp:9500
npx quasar dev -m capacitor -T android

Where patch-quasar.js simply removes the offending code from the library. This is not ideal. How can I do this without having to hack the code?

patch-quasar.js:

const fs = require('fs')
const path = require('path')

// Here we remove code from the quasar library that forces the host to be an external IP.
const filePath = path.join('node_modules', '@quasar', 'app-vite', 'lib', 'quasar-config-file.js')
const codeToRemove = `  else if (
    [ 'cordova', 'capacitor' ].includes(mode)
    && (!host || [ '0.0.0.0', 'localhost', '127.0.0.1', '::1' ].includes(host.toLowerCase()))
  ) {
    const getExternalIP = require('../lib/helpers/get-external-ip')
    host = await getExternalIP()
    this.chosenHost = host
  }\n`

fs.readFile(filePath, 'utf8', (err, data) => {
  if (err) {
    console.error('Error reading file:', err)
    return
  }

  const updatedData = data.replace(codeToRemove, '')

  fs.writeFile(filePath, updatedData, 'utf8', (err) => {
    if (err) {
      console.error('Error writing file:', err)
    }
  })
})

I also have the same problem/request

@rstoenescu, would it be possible to allow capacitor mode to run on localhost?

Avoids capacitor.config.json changes cluttering commits and causing merge conflicts.

This point is solved in app-vite v3(not released yet) through using capacitor.config.js/ts, and a wrapper under the hood which passes the used settings(e.g. ip, cleartext, etc.) via env variables.
